I have a wet/dry refugium, protien skimmer. Thats all I'm familiar with.
If you go to my link or Sooju's you will see two different styles of sponge filters. A sponge filter draws water through the sponge via powerhead or airlift tube where bacteria colonizes. This would be a form of biological filtration that is relatively cheap to set up, yet efficient enough to eliminate NH3
. The downside is that they can clog easily, but that would not be a problem if you maintained regular water changes (at the very least 25% daily or 50% every other day).
A biowheel usually refers to Marineland filtration systems where an hob
filter draws in water, passes through several stages (mechanical/chemical), and eventually cascades over a water wheel mixing oxygen into the water so bacteria can colonize. Here is the filter, but I don't care for them: Aquarium Power Filters: Marineland Penguin BIO-Wheel Power Filters
